Many plants found in nature have been used to treat various illnesses. One such plant is oregano (Kekik in Turkish). Health beneficial effects of carvacrol obtained from oregano oil have been shown scientifically. We have investigated the comparative effects of carvacrol in the liver of rats subjected to ischemia-reperfusion defect, with silymarin. To test(More)
BACKGROUND/AIM In the present study our purpose was to investigate the effect of pentoxyfilline, that plays a role in microcirculation and tissue oxygenation, alone and in combination with an antioxidant vitamin E on tissue damage in the rat liver induced by ischemia-reperfusion. METHODOLOGY Thirty-one albino rats were divided into four groups. Rats in(More)
The objective of this study was to examine whether a decrease in neutrophil-mediated tissue injury using Fucoidin, a nontoxic neutrophil rolling inhibitor, would improve flap survival in an island flap model after ischemia-reperfusion. Myeloperoxidase activity (an indirect index of tissue neutrophil count) and malondialdehyde (an indicator of lipid(More)
BACKGROUND Neurological injury because of transient cerebral ischemia is a potential complication of cardiovascular surgery. In this study, the neuroprotective effects of L-carnitine, vitamin E, and the combination of these agents on ischemia/reperfusion (I/R) injury were determined in a rat model of transient global cerebral I/R. METHODS Rats were(More)
In the study, the effects of relatively high single-dose of Ochratoxin A (OTA) and the antioxidant effects of Melatonin (Mel) and Coenzyme Q10 (CoQ10) on OTA-induced oxidative damages in rats were investigated. A total of 28 male Sprague-Dawley rats were divided into four groups of 7 rats each: Control, OTA, Mel+OTA and CoQ10+OTA groups. Malondialdehyde(More)
Melatonin (MEL) and coenzyme Q10 (CoQ10) both display antioxidant and free radical scavenger properties. In the present study, the effect of MEL and CoQ10 on the oxidative stress and fibrosis induced by ochratoxin A (OTA) administration in rats was investigated. Rats were divided into five equal groups, each consisting of seven rats: (1) controls; (2)(More)
Benzo(a)pyrene (B(a)P) is a polycyclic aromatic hydrocarbon with carcinogenic and toxic effects. Doxorubicin is a DNA-interacting drug widely used in chemotherapy. In the present study we investigated the effects of doxorubicin on rats that received benzo(a)pyrene. Sprague-Dawley male rats, 3-4 months old, were divided into 5 groups (n=9 per group). Group 1(More)
BACKGROUND/AIMS The deleterious effects of intestinal ischemia-reperfusion on liver are realized, but its effect on the regenerative capacity of the liver has not been studied. Our aim in this study was to determine the effect of intestinal ischemia-reperfusion on liver regeneration. METHODOLOGY Sprague-Dawley rats were randomly divided into six groups;(More)
BACKGROUND There are many experimental studies showing that increased intraabdominal pressure (IAP) reduces liver blood flow, leading to ischemia and portal venous congestion. But, there is no study evaluating the effect of increased IAP on liver regeneration. It is well known that acute liver ischemia and portal venous congestion impair liver regeneration.(More)
The present study aims to investigate the possible effects of carvacrol obtained from origanum oil upon the regenerative feature of the liver subsequent to partial hepatectomy in rats. Male Wistar Albino rats, weighing 230+/-30g, were divided into three experiment groups. Group I (n=8) were used as sham operation group. Group II (n=8) were applied saline(More)
